(The default value is 3.)The interval between retries is fixed at 30 seconds. The number of retries and the retryinterval can be used in conjunction with other sending components.If an address error (#550) is detected while connecting, sending is not retried. Images are notresent (retried) in Full Mode if the delivery confirmation results (MDN) report an error from thereceiving machine.Holding Send RequestsWhen several faxes are sent simultaneously via I-Fax, the status of the 5th job becomes“sending”.The status of the 6th job becomes “waiting”.For example, if the settings have been configured so that an error is generated when a fax issent via I-Fax, the status of the 6th job becomes “waiting” when 6 jobs are input continuouslyduring sending retry.“Sending” and “waiting” are displayed on the job status screen.
